Description

The new interface module in narrow MIRO casing is able to be used The new interface module in narrow MIRO casing is able to be used

universally. An analogue voltage or current, these are applied to three universally. The frequency, that is applied on the three inputs, will be

voltage (frequency) on all three outputs symmetrical to disposition. outputs symmetrical to disposition.

The output frequencies are through a 4-pole switch separable in

relation to 1:2, 1:4 and 1:8.
